I've tested it out a bit, and IOhannes and Ivica are right: it's a cleanup problem, rather something else. (It happens also when there is and there was no patch open).

 

Does it help to toggle DSP off and on, when Pd is in this post-suspend
mode? I had the impression it did, but I wasn't sure if it was just a
coincident, that CPU usage stopped at the same moment.

Yes! I was actually toggling DSP on and off, because I usually keep it off. When I switched it on, CPU usage instantly dropped to normal.

Seems like a symptom that is avoidable...
